FartsApp makes your phone fart on its own at random times. It runs in the background, works offline, and is built around anticipation and randomness. Choose how many farts per hour you want, press START, and let your phone decide when it happens. Fart sounds are random, and during an active session, no sound repeats until every available sound has been played. The free version includes 5 sounds, while Premium unlocks 100+ sounds and higher fart-per-hour settings.
